How do i get the number of how many objects my array holds?

Hi, I have an object named "cart"

everytime i push a button i add a new object with different strings to the array named "cart"

I want to return the total number of how many different objects i have inserted to the cart. but cart.length; return the number of strings and not the number of objects.

any ideas?

:point_right: There are a few ways to do this, here's some generic hints:

  • restructure the array to hold objects instead of individual strings
  • keep the object count in a separate variable, and increment it anytime you add a new object
  • add a special method to the array to compute the number of objects and use that instead of the length property

Be sure to post your code if you need more specific advice.
